<h1 id="reserved-words" class="docs">List of reserved words (macros, strings, registers)</h1>

<p>
The following is a list of reserved words used by mom.  Before
changing the name of any macro or document element tag with
<a href="goodies.html#ALIAS">ALIAS</a>,
I strongly recommend doing a search of this page for your proposed
new name.  If you find it in the left hand column, choose something
else instead.
</p>

<p>
Anyone interested in hacking/patching mom&#8217;s macro file
(om.tmac) will also find this list useful since it lists most of
the macros, strings, diversions, aliases, and number registers
mom uses, along with brief descriptions of their functions.
</p>

<p>
The list is not exhaustive.  PDF-related macros, strings, registers,
and diversions, as well as those associated with preprocessor
support and &#8220;Lists of&#8221; are not included.

<span style="display: block; margin-top: -1em;">Please note:</span>
Prior to version 1.1.9, all macros that included the word COLOR had
aliases that used COLOUR instead.  This convenience has now been
removed, in an effort to reduce the size of the om.tmac file.

  Furthermore, if you want the convenience, you'll have to edit the
om.tmac file.  Simply aliasing, say, HEAD_COLOR as HEAD_COLOUR will
not work, owing to significant changes in the handling of
docelement control macros that end in _COLOR.

<span style="display: block; margin-top: -1.5em; margin-bottom: -2.5em;">+++These aliases are for convenience, and header/footer management+++</span>
